Multimodal document reception apparatus and multimodal document transmission apparatus, multimodal document transmission/reception system, their control method, and program

ABSTRACT

Modality information indicating various functions of a multimodal document reception processing apparatus is transmitted to a multimodal document transmission apparatus, and a multimodal document, which is generated by the multimodal document transmission apparatus based on the modality information is received. A speech synthesis unit synthesizes speech of text data to be output as speech in the multimodal document, and a speech output unit outputs the synthesized output speech. A GUT display unit displays text data to be displayed in the multimodal document.

FIELD OF THE INVENTION

[0001] The present invention relates to a multimodal document reception apparatus for receiving a multimodal document that contains at least a description of an output style of text data from a multimodal document transmission apparatus via a network, a multimodal document transmission apparatus for generating a multimodal document and transmitting it to a multimodal document reception apparatus via a network, and a multimodal document transmission/reception system which is formed by connecting these multimodal document reception apparatus and multimodal document transmission apparatus via a network.

BACKGROUND OF THE INVENTION

[0002] With the popularization of the Internet, the world of Web browsing that displays documents, which are held in servers connected to the Internet and are described in HTML (Hyper Text Markup Language), on browsers of the personal computer is still growing.

[0003] In an HTML document, fields that describe a document structure and fields that describe an expression style are mixed due to its historical circumstance. As a format that separates the structure and style, CSS (Cascading Style Sheet) which extracts the expression style from the structure is also prevalent.

[0004] Even when CSS (expression style) is separated from HTML (document structure+expression style), since the document structure of HTML is designed in consideration of the expression style, a method of describing in XML (extensible Markup Language) that expresses only the tree structure of document contents, and XSL (extensible Stylesheet Language) that converts the tree structure into an expression style to be expressed is also spreading.

[0005] Java Script, VBScript, and the like are available as script languages which describe manipulations in HTML, and can describe in an HTML file or can be inserted as an external file.

[0006]FIGS. 32 and 33 show examples of documents described using XML and XSL, and FIGS. 34 to 37 respectively show examples of an HTML document and CSS file generated based on these documents, an example of a JavaScript file, and a display example of a browser.

[0007] Note that this browser is installed on a versatile computer such as a personal computer or the like. When the browser is launched in response to user's operation using an input device such as a mouse, keyboard, or the like, its browser window is displayed on a display.

[0008] When the user presses a “reverse” button 2501 on a browser window 2500 in FIG. 37, the contents of onClick in FIG. 34 are called, and the background and text colors in the browser window 2500 are reversed by a function (reverseColor ( )) described in JavaScript shown in FIG. 36.

[0009] As described above, when various stylesheets such as CSS, XSL, and the like are prepared, and are switched as needed, a single XML document that indicates only the tree structure of the document contents can be switched in accordance with purposes intended. Also, a script language can describe actions to be taken upon, e.g., depression of buttons.

[0010] Meanwhile, the performances of not only personal computers but also mobile terminals such as portable phones, PHS (Personal Handyphone System), PDA (Personal Digital Assistant), and the like, that users carry about everyday, have improved, and high-end mobile terminals have processing performance equivalent to that of a personal computer one generation before.

[0011] Such high-end mobile terminals have the following features.

[0012] (1) Mobile terminals can establish connection to a host computer via a public network or wireless LAN and can make data communications.

[0013] (2) Most of mobile terminals have audio input/output devices (microphone, loudspeaker, and the like).

[0014] However, the high-end mobile terminal has a small GUI (Graphic User Interface) window, i.e., poor display performance of GUI information. As commercially available mobile terminals, many non-high-end mobile terminals are present in addition to high-end terminals, and some of such mobile terminals cannot display GUI information.

[0015] Under such circumstances of mobile terminals, it is significant to implement a multimodal interface that can make some or all of operations and responses by means of speech.

[0016] Upon dealing with multimodal documents, some high-end mobile terminals can perform speech recognition and speech synthesis. However, the rest of mobile terminals cannot perform speech recognition and speech synthesis or can perform only poor speech recognition and speech synthesis.

[0017] However, technical advances and size reductions of hardware may allow models, which cannot perform an audio process so far, for the audio process. Most of mobile terminals have a small display screen due to portability. However, with the advent of high-definition display screens and lightweight hardware, even a mobile terminal can display many kinds of information on its display screen.

[0018] Furthermore, even with a mobile terminal having both audio and GUI modalities, the user may want to make a speech-only process in an environment in which he or she can hardly operate GUI or to make a GUI-only process in an environment in which he or she does not want to use speech inputs/outputs.

SUMMARY OF THE INVENTION

[0019] The present invention has been made in consideration of the above situation, and has as its object to provide a multimodal document reception apparatus and multimodal document transmission apparatus, a multimodal document transmission/reception system, their control method, and a program, which can provide an interface with an optimal modality in accordance with the modalities of individual terminals having a plurality of kinds of modalities, and those which the user wants to use.

[0020] According to the present invention, the foregoing object is attained by providing a multimodal document reception apparatus for receiving a multimodal document which contains at least a description of an output style of text data from a multimodal document transmission apparatus via a network, comprising; communication means for transmitting modality information indicating various functions of the multimodal document reception apparatus to the multimodal document transmission apparatus, and receiving a multimodal document, which is generated by the multimodal document transmission apparatus based on the modality information; speech synthesis means for synthesizing speech of text data to be output as speech in the multimodal document; speech output means for outputting output speech synthesized by the speech synthesis means; and display means for displaying text data to be displayed in the multimodal document.

[0076] The detailed arrangement of the multimodal document edit/transmission apparatus 102 will be described below using FIG. 3.

[0077]FIG. 3 is a detailed block diagram of the multimodal document edit/transmission apparatus according to the first embodiment of the present invention.

[0078] Referring to FIG. 3, reference numeral 301 denotes an Internet communication unit for receiving an original document from an external Web server (e.g., 103 a) via the Internet 104.

[0079] Reference numeral 302 denotes an original document holding unit for holding the original document acquired by the Internet communication unit 301. Reference numeral 303 denotes a stylesheet/script holding unit for holding an edit/manipulation file including stylesheets used to edit original documents held by the original document holding unit 302, and script files that describe manipulations of the original documents.

[0080] Reference numeral 304 denotes a data communication unit for receiving GUI operation information and modality information from the multimodal document reception processing apparatus 101, and transmitting a multimodal document, stylesheet, and script file to the multimodal document reception processing apparatus 101.

[0081] Reference numeral 305 denotes a terminal information holding unit for holding terminal information and modality information, which are received by the data communication unit 304 and are used to specify the multimodal document reception processing apparatus 101, for each individual multimodal document reception processing apparatus 101. Note that the terminal information holding unit 305 specifies each multimodal document reception processing apparatus 101 using a telephone number if the apparatus 101 is connected via a public line, or using an IP address if the apparatus 101 is connected via a wireless LAN or the like, and holds terminal information of each individual multimodal document reception processing apparatus 101.

[0082] Reference numeral 306 denotes a stylesheet/script determination unit for determining a stylesheet to be applied to an original document to be transmitted and a script file to be appended to the original document, on the basis of the modality information of the multimodal document reception processing apparatus 101 in communication, which is stored in the terminal information holding unit 305.

[0083] Reference numeral 307 denotes a transmission document edit unit for editing an original document, which is obtained based on the operation input received by the data communication unit 304 and is held by the original document holding unit 302, by applying the stylesheet and script file determined by the stylesheet/script determination unit 306, so as to generate a multimodal document.

[0084] Reference numeral 308 denotes a bus that interconnects the building components 301 to 307 of the multimodal document edit/transmission apparatus 102.

[0085] The operation of the multimodal document reception processing apparatus 101 will be described below using FIG. 4.

[0086]FIG. 4 is a flow chart showing the operation flow of the multimodal document reception processing apparatus according to the first embodiment of the present invention.

[0087] In step S401, the data communication unit 205 transmits modality information held by the modality information holding unit 204 to the multimodal document edit/transmission apparatus 102.

[0088] In step S402, the control waits for user's input. If user's input is detected (YES in step S402), the flow advances to step S403.

[0089] It is checked in step S403 if the user's input is a speech input. If the user's input is a speech input (YES in step S403), the flow advances to step S404, and the speech recognition unit 202 recognizes input speech to obtain a speech recognition result as user's GUI operation. The flow then advances to step S405. On the other hand, if the user's input is not a speech input (NO in step S403), the flow advances to step S405.

[0090] Note that the checking step S403 is implemented based on the presence/absence of input from the speech input unit 201.

[0091] It is checked in step S405 if the user's input is a change in modality information. If the user's input is a change in modality information (YES in step S405), the flow returns to step S401. On the other hand, if the user's input is not a change in modality information, the flow advances to step S406.

[0092] In step S406, the data communication unit 205 transmits the user's input (e.g., a multimodal document request) to the multimodal document edit/transmission apparatus 102. In step S407, the data communication unit 205 receives a multimodal document from the multimodal document edit/transmission apparatus 102.

[0093] It is checked in step S408 if the received multimodal document contains text data which is to undergo speech synthesis. If the received multimodal document contains text data which is to undergo speech synthesis (YES in step S408), the flow advances to step S409, and the speech synthesis unit 206 synthesizes speech of the text data which is to undergo speech synthesis. In step S410, the speech output unit 207 outputs the synthesized speech data.

[0094] Note that the checking process in step S408 is done by seeing if a speech synthesis function is held as modality information by the modality information holding unit 204, and the multimodal document received from the multimodal document edit/transmission apparatus 102 contains a predetermined tag (e.g., “<voice>” tag to be described later) for speech synthesis.

[0095] On the other hand, if it is determined in step S408 that the received multimodal document does not contain any text data which is to undergo speech synthesis (NO in step S408), the flow advances to step S411, and the GUI display unit 208 makes GUI display based on GUI display data in the received multimodal document. The flow then returns to step S402.

[0096] The operation of the multimodal document edit/transmission apparatus 102 will be explained below using FIG. 5.

[0097]FIG. 5 is a flow chart showing the operation flow of the multimodal document edit/transmission apparatus according to the first embodiment of the present invention.

[0098] In step S501, the data communication unit 304 waits for an input from the multimodal document reception processing apparatus 101. If an input is detected (YES in step S501), the flow advances to step S502.

[0099] It is checked in step S502 if the input from the multimodal document reception processing apparatus 101 is modality information. If the input is not modality information (NO in step S502), the flow jumps to step S505. On the other hand, if the input is modality information (YES in step S502), the flow advances to step S503, and the terminal information holding unit 305 holds that modality information and terminal information of the multimodal document reception processing apparatus 101. In step S504, a stylesheet and script to be applied to an original document to be transmitted are determined based on the received modality information.

[0100] In step S505, the Internet communication unit 301 acquires an original document via the Internet 104 on the basis of the input from the multimodal document reception processing apparatus 101, and holds it in the original document holding unit 302. In step S506, the transmission document edit unit 307 executes a transmission document edit process for applying the stylesheet determined by the stylesheet/script determination unit 306 to the original document held by the original document holding unit 302, thus generating a multimodal document.

[0101] In step S507, the data communication unit 304 transmits the multimodal document edited by the transmission document edit unit 307 to the multimodal document reception processing apparatus 101, and the flow returns to step S501.

[0102] An example of a multimodal document to be transmitted from the multimodal document edit/transmission apparatus 102 to each multimodal document reception processing apparatus 101 will be described below using FIG. 6.

[0103]FIG. 6 shows an example of a multimodal document according to the first embodiment of the present invention.

[0104] Referring to FIG. 6, text data bounded by “<voice>” and “</voice>” tags is that to be output as speech. The speech synthesis unit 206 synthesizes speech of this text data, which is output from the speech output unit 207. Text data bounded by “<h1>” and “</h1>” tags and by “<h2>” and “</h2>” tags are those to be displayed (GUI display data), and the GUI display unit 208 makes display, as shown in FIG. 7.

[0105] Note that an example of an original document and an example of a stylesheet to be applied to the original document are shown in FIGS. 8 and 9, and the transmission document edit unit 307 generates the multimodal document shown in, e.g., FIG. 6, on the basis of these original document and stylesheet.

[0106] In this example, the multimodal document edit/transmission apparatus 102 determines based on the modality information of the multimodal document reception processing apparatuses 101 that the multimodal document reception processing apparatuses 101 have the speech synthesis function and GUI display function. FIG. 9 shows a style sheet that specifies text data bounded by “<pageTitle>” and “</pageTitle>” tags, “<aTitle>” and “</aTitle>” tags, and “<abstract>” and “</abstract>” tags as GUT display data, and specifies text data bounded by “<details>” and “</details>” tags as text data to be output as speech.

[0107] As described above, according to the first embodiment, each multimodal document reception processing apparatus 101 sends modality information that the self apparatus uses to the multimodal document edit/transmission apparatus 102. The multimodal document edit/transmission apparatus 102 determines a stylesheet and script file to be applied to an original document to be transmitted on the basis of the received modality information, and sends back a multimodal document obtained by editing the original document and the script file if necessary on the basis of the determination result to the multimodal document reception processing apparatus 101. The multimodal document reception processing apparatus 101 can make multimodal output on the basis of the received multimodal document and script file.

[0108] That is, an optimal user interface environment can be provided to a terminal in accordance with the modalities of each individual terminal (multimodal document reception processing apparatus 101), which can communicate with a host computer (multimodal document edit/transmission apparatus 102) via a public line, wireless LAN, or the like, and has various modalities, or modalities that the user wants to use.

[0109] <Second Embodiment>

[0110] In the description of the first embodiment, the multimodal document reception processing apparatus 101 has modality information including the speech synthesis function and GUI display function. On the other hand, a multimodal document reception processing apparatus 101 which does not have any speech synthesis function can make GUI display shown in FIG. 12 on the basis of, e.g., an HTML file shown in FIG. 10 and a script file shown in FIG. 11.

[0111] In this case, all text data bounded by respective pairs of tags in the HTML file in FIG. 10 are GUI display data, and the script file in FIG. 11 is programmed to make GUI display shown in FIG. 12, and that shown in FIG. 13 when the user changes a menu in GUI display in FIG. 12 from “summary” to “details”.

[0112] <Third Embodiment>

[0113] When the multimodal document reception processing apparatus 101 has a small display screen like that of a portable terminal, GUI display shown in FIG. 15 can be made on the basis of, e.g., a script file shown in FIG. 11 and an HTML file shown in FIG. 14.

[0114] In this case, the contents of GUI display can change as shown in FIGS. 16 and 17 when the user selects menu items “headline”, “summary”, and “details” in GUI display in FIG. 15 in turn. That is, controls such as menus, buttons, and the like, which control to display/non-display text data to be displayed, are formed in GUI display data.

[0115] <Fourth Embodiment>

[0116] In the first embodiment, when a multimodal document is output to the multimodal document reception processing apparatus 101 having the speech synthesis unit 206, GUI display data and text data which is to undergo speech synthesis in that multimodal document are respectively output. However, the output styles of the GUI data and text data which is to undergo speech synthesis are not limited to such specific styles. For example, upon outputting a multimodal document for the first time, a speech synthesis execution button (control) that controls whether or not to execute speech synthesis may be displayed on a GUI by the same method described in the second and third embodiments without synthesizing speech of text data which is to undergo speech synthesis, and speech synthesis of that text data may be executed only when the user presses the speech synthesis execution button on GUI display.

[0117] <Fifth Embodiment>

[0118] As for the presence/absence of the speech recognition unit 202 in the multimodal document reception processing apparatus 101, if the apparatus 101 has no speech recognition unit 202, GUI display shown in, e.g., FIG. 18 is made. However, if the apparatus 101 has the speech recognition unit 202, buttons (i.e., icons that represent microphones) may be displayed at positions where speech recognition can be made, as shown in, e.g., FIG. 19, so as to inform the user that speech synthesis is allowed.

[0119] <Sixth Embodiment>

[0120] In the first to fifth embodiments, the multimodal document transmission/reception system implemented when each multimodal document reception processing apparatus 101 has the speech recognition function and speech synthesis function has been explained. However, in some cases, the multimodal document reception processing apparatus 101 has a speech input function but has neither the speech recognition function nor speech synthesis function or has poor ones if it has, and GUI operations by means of speech input/output are to be implemented in such multimodal document reception processing apparatus 101.

[0121] In the sixth embodiment, as an application example of the first embodiment, even when the multimodal document reception processing apparatus 101 has a speech input function but has neither the speech recognition function nor speech synthesis function or has poor ones if it has, and GUI operations by means of speech input/output are to be implemented in such multimodal document reception processing apparatus 101, a multimodal document transmission/reception system that can obtain the same effect as in the first embodiment by executing speech recognition and speech synthesis on the multimodal document edit/transmission apparatus 102 side will be explained.

[0122] In the multimodal document transmission/reception system of the sixth embodiment, speech data to be exchanged between the multimodal document reception processing apparatus 101 and multimodal document edit/transmission apparatus 102 uses encoded digital speech data. Hence, data security can be assured.

[0123] The detailed arrangement of one of the multimodal document reception processing apparatuses 101 will be described below using FIG. 20.

[0124]FIG. 20 is a detailed block diagram of the multimodal document reception processing apparatus according to the sixth embodiment of the present invention.

[0125] Referring to FIG. 20, reference numeral 401 denotes a speech input unit with which the user inputs speech via a microphone. Reference numeral 402 denotes an input speech encoding unit for encoding speech input from the speech input unit 401.

[0126] Reference numeral 403 denotes a GUI operation input unit for inputting GUI operations by means of a pointing device such as a stylus or the like, buttons of a ten-key pad, and the like. Reference numeral 404 denotes a modality information holding unit for holding modality information indicating various effective functions of the multimodal document reception processing apparatus 101.

[0127] FIGS. 24 to 26 show examples of modality information respectively when the multimodal document reception processing apparatus 101 is a portable phone, PHS, and PDA.

[0128] For example, FIG. 24 shows modality information when the multimodal document reception processing apparatus 101 is a portable phone. In FIG. 24, the input and output functions of the multimodal document reception processing apparatus 101 are described using an XML document.

[0129] Reference numeral 2410 denotes a description indicating the input function. Fields bounded by pairs of tags in lines 2411 to 2416 in this description 2410 correspond to detailed descriptions of practical input functions. The description 2410 includes descriptions indicating that input functions of speech input via a microphone (2411), text input via a ten-key pad (2412), pointing such as selection of items using a button (2413), movement of focus using a 4-way button (2414), and vertical screen scroll using a 2-way button (2416) are available, and a description indicating that horizontal screen scroll is not available (2415).

[0130] On the other hand, reference numeral 2420 denotes a description indicating the output function. Fields bounded by pairs of tags in lines 2421 to 2425 in this description 2420 correspond to detailed descriptions of practical output functions. The description 2420 includes descriptions indicating that output functions of speech output via a loudspeaker (2421), speech output via an earphone (2422), screen type=bitmap (2423), screen size=100 dots×120 dots (2424), and 16-level RGB color (2425) are available.

[0145] Referring to FIG. 21, reference numeral 501 denotes an Internet communication unit for receiving an original document from an external Web server (e.g., 103 a) via the Internet 104.

[0146] Reference numeral 502 denotes an original document holding unit for holding the original document acquired by the Internet communication unit 501.

[0153] The operation of the multimodal document reception processing apparatus 101 will be described below using FIG. 22.

[0154]FIG. 22 is a flow chart showing the operation flow of the multimodal document reception processing apparatus according to the sixth embodiment of the present invention.

[0155] In step S901, the data communication unit 407 transmits modality information held by the modality information holding unit 404 and user setup information held by the user setup holding unit 406 to the multimodal document edit/transmission apparatus 102.

[0156] In step S902, the data communication unit 407 receives a multimodal document and encoded output speech data or a speech recognition result corresponding to text data to be output as speech in that multimodal document from the multimodal document edit/transmission apparatus 102. In step S903, the GUI display unit 410 makes GUI display based on GUI display data in the multimodal document. In step S904, the output speech decoding unit 408 decodes encoded output speech data, and the speech output unit 409 outputs speech of the output speech data.

[0157] It is checked in step S905 if the speech recognition result is received from the multimodal document edit/transmission apparatus 102. If the speech recognition result is received (YES in step S905), the flow advances to step S907; otherwise (NO in step S905), the flow advances to step S906 to wait for user's input (NO in step S906). On the other hand, if user's input is detected (YES in step S906), the flow advances to step S907.

[0158] It is checked in step S907 if the user's input is a change in user setup information. If the user's input is a change in user setup information (YES in step S907), the flow advances to step S908 to execute a change holding process, i.e., to hold the user setup information that has been changed by the user in the user setup holding unit 406. The flow then returns to step S901. On the other hand, if the user's input is not a change in user setup information (NO in step S907), the flow advances to step S909.

[0159] It is checked in step S909 if the user's input is a speech input. If the user's input is a speech input (YES in step S909), the flow advances to step S910 to encode input speech, and the flow then advances to step S911. On the other hand, if the user's input is not a speech input (NO in step S909), the flow advances to step S911.

[0160] In step S911, the data communication unit 407 transmits the user's input to the multimodal document edit/transmission apparatus 102, and the flow returns to step S902.

[0161] The operation of the multimodal document edit/transmission apparatus 102 will be explained below using FIG. 23.

[0162]FIG. 23 is a flow chart showing the operation flow of the multimodal document edit/transmission apparatus according to the sixth embodiment of the present invention.

[0163] In step S1001, the data communication unit 504 waits for an input from the multimodal document reception processing apparatus 101. If an input is detected (YES in step S1001), the flow advances to step S1002.

[0164] It is checked in step S1002 if the input from the multimodal document reception processing apparatus 101 is modality or user setup information. If the input is modality or user setup information (YES in step S1002), the flow advances to step S1003, and the terminal information holding unit 505 holds the modality or user setup information together with the terminal information of the multimodal document reception processing apparatus 101. The flow then advances to step S1004.

[0165] In step S1004, the Internet communication unit 501 acquires an original document requested by the multimodal document reception processing apparatus 101 via the Internet 104, and holds it in the original document holding unit 502.

[0166] In step S1005, the stylesheet determination unit 506 determines a stylesheet to be used on the basis of the modality or user setup information held by the terminal information holding unit 505. In step S1006, the transmission document edit unit 508 executes a transmission document edit process for applying the stylesheet determined by the stylesheet determination unit 506 to the original document held by the original document holding unit 502, thus generating a multimodal document.

[0167] In step S1007, the speech synthesis unit 509 synthesizes speech of text data which is to undergo speech synthesis (e.g., data appended with “<text-to-speech>” tags to be described later) in the multimodal document edited by the transmission document edit unit 508, thereby generating encoded output speech data. In step S1008, the data communication unit 504 transmits the multimodal document edited by the transmission document edit unit 508, and the encoded output speech data to the multimodal document reception processing apparatus 101, and the flow returns to step S1001.

[0168] On the other hand, if it is determined in step S1002 that the input is neither modality information nor user setup information (NO in step S1002), the flow advances to step S1009 to check if the input from the multimodal document reception processing apparatus 101 is a speech input. If the input is a speech input (YES in step S1009), the flow advances to step S1010, and the speech recognition unit 507 recognizes encoded input speech data. In step S1011, the data communication unit 504 transmits a speech recognition result to the multimodal document reception processing apparatus 101, and the flow then returns to step S1001.

[0169] If it is determined in step S1009 that if the input is not a speech input (NO in step S1009), i.e., if the input is GUI operation information, the flow advances to step S1012. In step S1012, a link document corresponding to the original document is acquired via the Internet communication unit 501 and Internet 104 in accordance with that GUI operation information, and is held in the original document holding unit 502. The flow then advances to step S1005.

[0170] An example of a multimodal document to be generated by the transmission document edit unit 508 will be explained below using FIGS. 29 to 31.

[0171]FIG. 29 shows an example of an original document, FIG. 30 shows an example of a stylesheet determined based on the modality information shown in FIG. 24 and user setup information shown in FIG. 27, and FIG. 31 shows a display example of GUI display data in a multimodal document generated based on these original document and stylesheet.

[0172] Referring to FIG. 31, according to the user setup information of the multimodal document reception processing apparatus 101 that displays GUI display data, large characters (e.g., Midtown cherry blossoms are in full bloom . . . ) and middle characters (e.g., April 3, Kanto Area . . . ) are displayed on the screen, and middle and small characters are read aloud by synthetic speech.

[0173] For this reason, the stylesheet determination unit 506 determines a stylesheet (FIG. 30) which converts “<aTitle>” and “</aTitle>” tags and “<abstract>” and “</abstract>” tags in the original document in FIG. 29 into “<h1>” and “</h1>” tags and by “<h2>” and “</h2>” tags, and also converts “<abstract>” and “</abstract>” tags and “<details>” and “</details>” tags into “<text-to-speech>” and “</text-to-speech>” tags.

[0174] The speech synthesis unit 509 generates encoded output speech data of text data bounded by “<abstract>” and “</abstract>” tags and “<details>” and “</details>” tags which are converted into “<text-to-speech>” and “</text-to-speech>” tags, in the multimodal document edit/transmission apparatus 102.

[0175] When a multimodal document, which contains this encoded output speech data and is obtained based on the original document in FIG. 29 and the stylesheet in FIG. 30, is transmitted to the multimodal document reception processing apparatus 101, the encoded output speech data is output as speech from the speech output unit 409 via the output speech encoding unit 408. A GUI shown in FIG. 31 is displayed on the GUI display unit 410 on the basis of GUI display data in the multimodal document. Since “<text-to-speech>” tags in FIG. 30 are bounded by “<!--” and “-->” tags (those indicating comment out), they are not displayed on the GUT.

[0176] As described above, according to the sixth embodiment, since the multimodal document edit/transmission apparatus 102 makes speech recognition and speech synthesis, the same effect as in the first embodiment can be obtained even when the multimodal document reception processing apparatus 101 has a speech input function but has neither the speech recognition function nor speech synthesis function or has poor ones if it has, and GUI operations by means of speech input/output are to be implemented in such multimodal document reception processing apparatus 101.

[0177] <Seventh Embodiment>

[0178] In the sixth embodiment, the modality information in FIG. 24 and the user setup information in FIG. 27 have been exemplified. If modality information and user setup information other than those described above are used, the same process can be applied if stylesheet corresponding to such information are prepared.

[0179] <Eighth Embodiment>

[0180] In the sixth embodiment, one, combined stylesheet is applied to an original document for the sake of simplicity. Alternatively, stylesheets may be prepared in correspondence with tags, and a plurality of stylesheets may be applied.

[0181] <Ninth Embodiment>

[0182] In the sixth embodiment, the stylesheet in FIG. 30 corresponding to the original document in FIG. 29 is transmitted to the multimodal document reception processing apparatus 101 while containing a description indicating that the contents within “<text-to-speech>” tags in the multimodal document are excluded from GUI display data. Alternatively, in order to reduce the data size of the multimodal document itself, a multimodal document from which the contents within “<text-to-speech>” tags are deleted may be transmitted to the multimodal document reception processing apparatus 101.

[0183] Note that the present invention includes a case wherein the invention is achieved by directly or remotely supplying a program of software that implements the functions of the aforementioned embodiments (a program corresponding to the flow charts shown in the respective drawings in the embodiments) to a system or apparatus, and reading out and executing the supplied program code by a computer of that system or apparatus.

That is, the present invention includes a WWW server which makes a plurality of users download a program file required to implement the functional process of the present invention by the computer.

[0188] Also, a storage medium such as a CD-ROM or the like, which stores the encrypted program of the present invention, may be delivered to the user, the user who has cleared a predetermined condition may be allowed to download key information that decrypts the program from a home page via the Internet, and the encrypted program may be executed using that key information to be installed on a computer, thus implementing the present invention.

[0189] The functions of the aforementioned embodiments may be implemented not only by executing the readout program code by the computer but also by some or all of actual processing operations executed by an OS or the like running on the computer on the basis of an instruction of that program.

[0190] Furthermore, the functions of the aforementioned embodiments may be implemented by some or all of actual processes executed by a CPU or the like arranged in a function extension board or a function extension unit, which is inserted in or connected to the computer, after the program read out from the recording medium is written in a memory of the extension board or unit.
